본 발명은 콜로이달 실리카를 함유한 Tetra ethoxy silane(TEOS)와 N-Octyltriethoxy silane(OFS-6341 silane) 및 희석재로 이루어진 친환경 세라믹 침투방수 강화제를 침투시켜 안정된 결정구조를 갖은 수밀방수 불용성 조직을 형성하고 실란화 방수포막을 조성하여 줌으로써, 물의 침입을 막고 구조물의 열화원인이 되는 각종 유해물질을 사전에 방지하여 강도 및 내구성을 증가시킬 수 있고, 콘크리트 구조물 대상면에 세라믹 침투방수 강화제를 도포하여 줌으로써, 흡수성 및 투수성을 감소시켜 탁월한 방수성을 부여하여 구조물의 수명을 연장할 수 있는 콘크리트 구조물의 세라믹 침투방수 강화제 조성물과 그 제조방법에 관한 기술이다.The present invention relates to a ceramic waterproofing agent composition for concrete structures and a method for manufacturing the same, which comprises an eco-friendly ceramic waterproofing agent comprising Tetra ethoxy silane (TEOS) containing colloidal silica, N-Octyltriethoxy silane (OFS-6341 silane), and a diluent, which forms a watertight waterproof insoluble tissue having a stable crystal structure and forms a silanized waterproof film, thereby preventing water intrusion and various harmful substances that cause deterioration of the structure in advance, thereby increasing strength and durability, and which extends the lifespan of the structure by applying the ceramic waterproofing agent to the surface of the concrete structure to provide excellent waterproofing properties by reducing absorbency and water permeability.
근래 들어 콘크리트 중성화에 대한 연구가 활발하게 진행되고 있으나, 중성화에 대한 대책을 살펴보면 콘크리트에 혼입되는 재료의 종류 및 조합조건은 중성화 진행속도에 커다란 영향을 미치므로 사용재료의 선정 및 조합조건의 결정시에는 콘크리트 자체의 품질이 가능한 한 치밀, 견고하도록 조강, 보통 포틀랜드 시멘트 사용, 고비중의 양질골재 사용, 혹은 물시멘트비, 공기량 등이 낮게 되도록 하여야 하고, 양생조건, 타설, 다짐방법 등의 시공인지의 영향이 크므로 현장 시공 시에는 충분한 초기양생과 소요부분의 내구성을 감안하여 콘크리트의 피복 두께를 충분히 상정하여야 하며, 타설 시에는 모르타르의 누출, 콘크리트의 분리, 피복콘크리트의 결손이 생기지 않도록 거포집의 제작 및 다짐방법 등에 대한 고려가 있어야 한다.Recently, research on concrete neutralization has been actively conducted, but when looking at countermeasures for neutralization, the type of materials mixed into concrete and the combination conditions have a great influence on the progress of neutralization, so when selecting materials to be used and determining the combination conditions, the quality of the concrete itself should be as dense and solid as possible, such as using early-strength and ordinary portland cement, using high-gravity, good-quality aggregates, or lowering the water-cement ratio and air content. In addition, since the construction conditions such as curing conditions, pouring, and compacting methods have a great influence, when constructing on-site, sufficient initial curing and the durability of the required area should be taken into account to sufficiently estimate the concrete cover thickness, and when pouring, consideration should be given to the production of foam boxes and the compacting method to prevent mortar leakage, concrete separation, and loss of cover concrete.
또한, 표면 마감재의 사용은 탄산가스 침입을 억제하여 중성화 속도를 지연시킬 수 있었다. 따라서 표면 마감재는 에폭시, 우레탄, 아크릴 수지 등의 고분자 계통이 억제효과가 있는 것으로 알려져 있다. 중성화의 진행은 콘크리트 표층부의 기포분포 특성의 탄산가스 확산의 이동으로 시작되므로, 콘크리트 표층부의 성질을 치밀화시킴으로 중성화 진행속도를 지연시킬 수 있다.In addition, the use of surface finishing materials could delay the neutralization rate by inhibiting the penetration of carbon dioxide gas. Therefore, it is known that surface finishing materials such as epoxy, urethane, and acrylic resins have an inhibitory effect. Since the progress of neutralization begins with the movement of carbon dioxide diffusion due to the bubble distribution characteristics of the concrete surface layer, the neutralization rate can be delayed by densifying the properties of the concrete surface layer.
일반적으로 콘크리트 구조물은 대기에 노출되어 시간이 경과함에 따라 자외선, 탄산가스, 산성비, 황사, 배기가스의 외부조건에 대한 저항력이 감소되어, 콘크리트가 중성화로 유도된다. 이러한 현상을 열화라고 하는데, 콘크리트는 무수히 많은 콘 구멍을 보유한 다공성 물질인 바, 수분이나 습기는 모세관을 통하여 보유하게 되므로 동-하절기의 온도 변화에 따른 수축-팽창과, 그리고 콘크리트구조물에 함유된 각종 유해물질과 공기(탄산가스, 질소성분) 및 수분과의 반응에 의해 균열이 발생하게 되고, 이러한 현상이 지속 반복 되면서, 열화로 인한 내부 철근이 부식되고 구조물에 치명적인 현상이 일어나게 된다.In general, concrete structures are exposed to the atmosphere and, over time, their resistance to external conditions such as ultraviolet rays, carbon dioxide, acid rain, yellow dust, and exhaust gas decreases, leading to the neutralization of the concrete. This phenomenon is called deterioration. Concrete is a porous material with countless pores, and moisture and humidity are retained through the capillaries. Therefore, cracks occur due to shrinkage and expansion according to temperature changes between winter and summer, and reactions between various harmful substances contained in the concrete structure and air (carbon dioxide, nitrogen components) and moisture. If this phenomenon is repeated continuously, the internal reinforcing bars corrode due to deterioration, causing fatal phenomena to the structure.
따라서 이와 같은 문제점을 해결하기 위해 기존에 여러 가지 도막방수제 및 모르타르 침투방수제 등을 많이 사용하고 있다.Therefore, to solve this problem, various types of waterproofing agents and mortar penetrating waterproofing agents are being widely used.
종래에 방수제는 지방산계 유지 혹은 탄화파라핀수소 화합물 및 에폭시수지와 우레탄계 또는 아크릴계와 라텍스 수지 등의 유기 고분자 계통의 수지를 유기용제나 물에 희석하여 사용해 왔으나, 고분자이기 때문에 침투되지 않고 콘크리트 표면에 도막의 형태로 코팅되어 건조 후 물리적인 에너지 즉 마찰에 의해 없어지거나, 모체와 이질제이므로 들떠서 분리되므로 방수의 기능이 상실된다.In the past, waterproofing agents were used by diluting organic solvents or water with fatty acid-based oils or hydrocarbon paraffin compounds and organic polymer resins such as epoxy resins, urethane resins, acrylic resins and latex resins. However, since they are polymers, they do not penetrate and are coated on the concrete surface in the form of a film, which disappears after drying due to physical energy, i.e. friction, or because they are heterogeneous with the parent material, they become lifted and separate, thus losing their waterproofing function.
또한. 모르타르 침투방수제로서는 실리카 시멘트에 혼합된 실리카(SiO2) 성분의 혼화재료로서 화산재, 규산백토, 응회암, 규조토 등의 천연 포졸란과 fly ash 등의 인공포졸란을 총칭하여 포졸란이라 하고, 이 포졸란은 모르타르에 혼입하여 사용함으로서 수밀성향상, 내황사염 저항성 향상, 장기강도 증진 등의 효과를 얻을 수 있어, 모르타르 침투방수재로 사용되고 있다. 하지만 방수층 보호 모르타르 및 코팅제와의 부착성 결핍으로 문제점이 있다.Also, as a mortar penetration waterproofing agent, natural pozzolans such as volcanic ash, siliceous clay, tuff, and diatomaceous earth and artificial pozzolans such as fly ash are collectively called pozzolans as an admixture of silica (SiO 2 ) components mixed in silica cement, and these pozzolans can be used by mixing them into mortar to improve watertightness, sulfur dioxide resistance, and long-term strength, and are thus used as mortar penetration waterproofing agents. However, there is a problem due to the lack of adhesion with waterproofing layer protection mortar and coating agents.
또한, 주로 교량에 사용되는 액상 침투방수제는 n-Octyltriethoxy silane 단량체에 희석제(주로 광유를 사용)를 혼합해 사용하고 있다. 그러나 방수층 보호 코팅제와의 부착성 부족으로 문제점이 있고, 수압을 받는 저수조, 하폐수조와 같은 콘크리트 구조물에는 사용이 불가능하다.In addition, liquid penetrating waterproofing agents mainly used for bridges are used by mixing a diluent (mainly mineral oil) with n-Octyltriethoxy silane monomer. However, there is a problem due to insufficient adhesion to the waterproofing layer protective coating agent, and it cannot be used in concrete structures such as water tanks and sewage tanks that are subject to water pressure.
그러므로 콜로이달 실리카를 함유한 Tetra ethoxy silane(TEOS)와 N-Octyltriethoxy silane(OFS-6341 silane) 및 희석재로 이루어진 친환경 세라믹 침투방수 강화제를 침투시켜 안정된 결정구조를 갖은 수밀방수 불용성 조직을 형성하고 실란화 방수포막을 조성하여 주어 물의 침입을 막고 구조물의 열화원인이 되는 각종 유해물질을 사전에 방지하여 강도 및 내구성을 증가시킬 수 있고, 흡수성 및 투수성을 감소시켜 탁월한 방수성을 부여하여 구조물의 수명을 연장할 수 있는 콘크리트 구조물의 세라믹 침투방수 강화제 조성물과 그 제조방법의 개발이 절실히 요구되고 있는 실정이다.Therefore, there is an urgent need for the development of a ceramic waterproofing reinforcing agent composition for concrete structures and a method for manufacturing the same, which can form a watertight waterproof insoluble tissue with a stable crystal structure by penetrating an eco-friendly ceramic waterproofing reinforcing agent composed of Tetra ethoxy silane (TEOS) containing colloidal silica, N-Octyltriethoxy silane (OFS-6341 silane), and a diluent, and form a silanized waterproof film to prevent water intrusion and various harmful substances that cause structural deterioration, thereby increasing strength and durability, and extending the lifespan of the structure by reducing absorbency and water permeability and imparting excellent waterproofing properties.

In describing the present invention, if it is determined that a detailed description of a related known technology or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. The terms described below are terms defined in consideration of their functions in the present invention, and since these may vary depending on the intention or custom of the user or operator, the definitions should be made based on the contents of the entire specification describing the ceramic waterproofing reinforcing agent composition for concrete structures and the manufacturing method thereof, which is the present invention.
이하, 본 발명의 바람직한 일실시예에 따른 콘크리트 구조물의 세라믹 침투방수 강화제 조성물을 상세히 설명한다.Hereinafter, a ceramic penetration waterproofing reinforcing agent composition for concrete structures according to a preferred embodiment of the present invention will be described in detail.
본 발명인 콘크리트 구조물의 세라믹 침투방수 강화제 조성물은 콜로이달 실리카 15 내지 25몰을 함유한 Tetraethoxy silane 15 내지 25 중량부와, N-Octyltriethoxy silane 15 내지 25 중량부와, 희석제 60 내지 70 중량부로 이루어진 것이다.The ceramic penetration waterproofing reinforcing composition of the present invention for concrete structures comprises 15 to 25 parts by weight of tetraethoxy silane containing 15 to 25 mol of colloidal silica, 15 to 25 parts by weight of N-Octyltriethoxy silane, and 60 to 70 parts by weight of a diluent.
상기 콜로이달 실리카 15 내지 25몰을 함유한 Tetraethoxy silane 15 내지 25 중량부와, N-Octyltriethoxy silane 15 내지 25 중량부로 이루어진 것이 수밀성이 양호하고 강도가 증가하며, 소수성이면서 비등이 없어 2차 코팅해 침투시킬 수 있고. 미립자 사이에 방수막을 형성하여 수분 침입을 막고, 열화요인이 되는 유해물질인 염화이온 및 CO2 가스를 사전에 차단하여 콘크리트의 중성화를 예방할 수 있는 것이다.The composition comprising 15 to 25 parts by weight of Tetraethoxy silane containing 15 to 25 moles of the colloidal silica and 15 to 25 parts by weight of N-Octyltriethoxy silane has excellent water tightness and increased strength, is hydrophobic and does not boil, and can be penetrated by a second coating. It forms a waterproof film between fine particles to prevent moisture intrusion and prevents neutralization of concrete by blocking chloride ions and CO2 gas, which are harmful substances that cause deterioration, in advance.
편의상 세라겔 EM-50으로 표기하는 것은 콘크리트 침투성 표면 강화제로서, 콜로이달 실리카 15 내지 25 몰을 함유한 테트라 에톡시 실란 화합물로이다.For convenience, it is indicated as Seragel EM-50, which is a concrete penetrable surface strengthening agent and is a tetraethoxy silane compound containing 15 to 25 mol of colloidal silica.
또한, 다른 바람직한 일 측면에 따른 졸-겔 조성물에 있어서, 세라겔 EM-50 5 내지 15 중량부와 OFS-6341 silane 25 내지 35 중량부로 이루어진 것은 깊이 침투되고, 알킬기 증가로 소수성으로 인한 발수성이 우수하나, 수압에는 약하고, 표면에 도막 코팅이 어렵고, 기계적인 물성이 약하다.In addition, in a sol-gel composition according to another preferred aspect, a composition comprising 5 to 15 parts by weight of Seragel EM-50 and 25 to 35 parts by weight of OFS-6341 silane penetrates deeply and has excellent water repellency due to hydrophobicity caused by an increase in alkyl groups, but is weak against water pressure, difficult to coat a film on the surface, and has weak mechanical properties.
또한, 바람직한 일 측면에 따른 졸겔 조성물에 있어서, 세라겔 EM-50 25 내지 35 중량부와 OFS-6341silane 5 내지 15 중량부로 이루어진 것은 수밀성, 강도, 내구력은 향상되나, 알킬기 감소로 수분을 흡수할 수 있고 기질 표면에 침투되지 않은 규산 물질이 불순물로 남아 있게 된다.In addition, in a sol-gel composition according to a preferred aspect, a composition comprising 25 to 35 parts by weight of Seragel EM-50 and 5 to 15 parts by weight of OFS-6341silane improves water tightness, strength, and durability, but due to a decrease in alkyl groups, moisture can be absorbed and silicic acid substances that have not penetrated the substrate surface remain as impurities.
또한, 본 발명의 다른 일 측면에 따른 졸-겔 조성물로부터 얻어진 세라겔 EM-50와 OFS-6341 silane의 혼합물을 이소프로필 알코올에 용해시켜 얻어진 조성물로, 내염, 방식, 방청, 내구성, 내마모성, 내수, 중성화 방지용 세라믹 침투방수 강화제가 최적인 것이다.In addition, a composition obtained by dissolving a mixture of Seragel EM-50 and OFS-6341 silane obtained from a sol-gel composition according to another aspect of the present invention in isopropyl alcohol is an optimal ceramic penetration waterproofing reinforcing agent for salt resistance, corrosion prevention, rust prevention, durability, wear resistance, water resistance, and neutralization prevention.
상술한, 테트라 에톡시 실란(Tetraethoxy silane)은 단독 또는 희석하여 적용하거나 포물레이션 제품의 첨가제로써 사용할 수 있는 순수한 실란으로, 천연석재 또는 다른 건축 재료에 적용하면, SiO2 바인다와 같은 실리카겔을 형성하여 기재의 강도를 증가시켜 주며, 상기 형성된 실록산 레진은 산성비 등에 매우 강한 저항성을 갖은 무기바인더이고, 매우 낮은 점도로 인해 큰 다공성 기질에 10 내지 20cm까지 침투할 수 있는 것이다.Tetraethoxy silane, as described above, is a pure silane that can be applied alone or in a diluted form or as an additive to a formulation product. When applied to natural stone or other building materials, it forms a silica gel such as a SiO 2 binder to increase the strength of the substrate, and the siloxane resin formed is an inorganic binder that has very strong resistance to acid rain, etc., and can penetrate 10 to 20 cm into a large porous substrate due to its very low viscosity.
또한, 상기 Tetraethoxy silane에 포함되어 있는 콜로이달 실리카는 용액상으로, 나트륨염을 0.1 내지 0.5중량부를 포함하고, 기타 물, 콜로이드 형성물질 및 pH 조절물질을 함유하고 있는 10 내지 20㎛의 초미립자 콜로이드 용액으로 pH는 8.5인 고형분 함량 28 내지 32중량부의 용액인 것이다.In addition, the colloidal silica contained in the tetraethoxy silane is a solution containing 0.1 to 0.5 parts by weight of a sodium salt, other water, a colloid forming substance, and a pH adjusting substance, and is a solution of ultrafine colloid particles of 10 to 20 ㎛ in diameter, having a pH of 8.5 and a solid content of 28 to 32 parts by weight.
또한, n-옥틸트리에톡시 실란(N-Octyltriethoxy silane)은 소형 분자이기 때문에 시멘트계 표면에 깊숙이 침투하며, 이 물질은 알카리성 또는 산성 환경의 대기 및 기질 내 습기와 반응해 수산기를 생성한다. 이러한 수산기는 기질 및 수산기 자체와 결합해 기질로의 수분 흡수를 방해하는 소수성처리가 이루어진다. 새로운 콘크리트와 같은 알카리성 환경은 반응을 촉진시키고 소수성 표면 형성을 가속화시키는 것이다.Also, because N-Octyltriethoxy silane is a small molecule, it penetrates deep into the cement surface, and this substance reacts with the atmosphere and moisture in the substrate in an alkaline or acidic environment to generate hydroxyl groups. These hydroxyl groups combine with the substrate and the hydroxyl groups themselves to form a hydrophobic treatment that prevents moisture absorption into the substrate. An alkaline environment such as new concrete promotes the reaction and accelerates the formation of a hydrophobic surface.
또한, 상기 희석제는 알코올 용매이고, 이소프로필 알콜을 용매 내에서 졸(sol)화될 수 있는 조성이며, 이러한 졸은 겔화를 거처 방수막을 형성하는 것이다.In addition, the diluent is an alcohol solvent and is a composition that can be sol-ized in isopropyl alcohol, and this sol forms a waterproof film through gelation.
상기 본 발명에 사용된 콜로이달 실리카와 테트라 에톡시 실란(Tetraethoxy silane Si(C2H5O)4)의 졸-겔 공정에 의한 조성물인 세라겔 EM-50은 콘크리트 내부로 침투되어 유리금속 이온과 반응하여 규산칼슘 겔을 형성하여 모세기공 및 공극을 채워주어 콘크리트를 수밀하게 만들어줄 뿐만 아니라, SiO2 바인다와 같은 실리카겔을 형성하여 콘크리트 강도를 증가 시켜주고, 형성된 실록산 레진은 산성비 등에 매우강한 저항성을 갖은 무기바인더이며, 매우 낮은 점도로 인해 큰 다공성 기질에 10 내지 20㎝까지 침투할 수 있는 것이다.The Ceragel EM-50, a composition obtained by a sol-gel process of colloidal silica and tetraethoxy silane (Si(C2H5O ) 4 ) used in the present invention, penetrates into concrete and reacts with free metal ions to form a calcium silicate gel, which fills pores and voids to make the concrete watertight, and also forms a silica gel such as a SiO2 binder to increase the strength of the concrete, and the formed siloxane resin is an inorganic binder with very strong resistance to acid rain, etc., and can penetrate 10 to 20 cm into a large porous substrate due to its very low viscosity.
그러나 이와 같은 알콕시 실란류 2종의 단량체을 채택하는 것만으로는 졸-겔 공정에 의해 제조되는 유-무기 하이브리드 유도 제품의 범용적인 사용을 위해 침투성의 확장, 콘크리트 내부의 수밀성, 수분 흡수를 방해하는 소수성 표면 형성, 수압에 견디는 방수성, 열화원인이 되는 염화이온 및 탄산가스 침입을 억제하는 조성물, 표면강도 등 해결해야 할 문제들이 많다.However, simply adopting these two types of alkoxy silane monomers still leaves many problems to be solved for the general use of organic-inorganic hybrid derived products manufactured by the sol-gel process, such as expanding permeability, watertightness inside concrete, formation of a hydrophobic surface that prevents moisture absorption, waterproofing that withstands water pressure, a composition that suppresses the intrusion of chloride ions and carbon dioxide, which are causes of deterioration, and surface strength.
그래서 콜로이달 실리카 15 내지 25몰을 함유한 Tetraethoxy silane 15 내지 25 중량부와, N-Octyltriethoxy silane 15 내지 25 중량부와, 희석제 60 내지 70 중량부로 이루어진 콘크리트 구조물의 세라믹 침투방수 강화제 조성물을 제공한 것이다.Accordingly, a ceramic penetration waterproofing reinforcing agent composition for concrete structures is provided, comprising 15 to 25 parts by weight of tetraethoxy silane containing 15 to 25 mol of colloidal silica, 15 to 25 parts by weight of N-Octyltriethoxy silane, and 60 to 70 parts by weight of a diluent.
상기 세라믹 침투방수 강화제는 콘크리트 내부로 침투되어 유리 금속이온과 결합해 규산칼슘 겔 및 실리카 겔을 형성하여 모세기공 및 공극을 채워주어 콘크리트를 수밀하게 만들고 콘크리트 강도를 증가시켜 주고, 상기 형성된 실록산 레진은 산성비에 매우 강하며, 알카리성 또는 산성 환경의 대기 및 기질 내 습기와 반응해 수산기를 생성 한다. 이러한 수산기는 기질 및 수산기 자체와 결합해 기질로의 소수성인 방수막을 형성해 물, 염화이온, 탄산가스등 유해물질 침입을 막아버린다. 새로운 콘크리트와 같은 알카리성 환경은 반응을 촉진시키고 소수성 표면 형성을 가속화시켜 주는 효력을 가진 콘크리트 표면이 개질화되어 내구성이 향상되고, 방수성, 내화학성, 내염수성, 내마모성 및 강도가 획기적으로 향상되며, 여전히 통기성이 있고, 수축-팽창의 능력을 유지하는 것이다.The above ceramic waterproofing reinforcing agent penetrates into the concrete and combines with free metal ions to form calcium silicate gel and silica gel, which fill pores and voids to make the concrete watertight and increase the strength of the concrete. The formed siloxane resin is highly resistant to acid rain and reacts with the atmosphere and moisture in the substrate in an alkaline or acidic environment to generate hydroxyl groups. These hydroxyl groups combine with the substrate and the hydroxyl groups themselves to form a hydrophobic waterproof film on the substrate, preventing the intrusion of harmful substances such as water, chloride ions, and carbon dioxide. An alkaline environment such as new concrete promotes the reaction and accelerates the formation of a hydrophobic surface, so that the concrete surface is modified, thereby improving durability, and dramatically improving waterproofness, chemical resistance, salt water resistance, wear resistance, and strength, while still being breathable and maintaining the ability to shrink and expand.

또한, 콘크리트 구조물의 세라믹 침투방수 강화제 시공방법은 시공면의 콘크리트 덩어리나 이물질, 오일 및 페인트를 제거한 후 돌출 부위는 제거하고 크랙이나 패인 곳은 수지 모르타르로 충진 처리하는 단계(S10)와; 숏 블라스트(shot blast) 또는 워터 젯(water jet)을 사용하여 잔사를 완전히 제거하여 콘크리트 시공면을 정돈하는 단계(S20)와; 상기 정돈된 콘크리트 시공면에 저압(5kg/㎠) 스프레이어로 시공 면에서 20cm 띄어 수직으로 0.3L/㎡을 도포 침투시키는 단계(S30); 을 구비한다.In addition, the method for constructing a ceramic penetration waterproofing reinforcing agent for a concrete structure comprises the steps of (S10) removing concrete lumps, foreign substances, oil, and paint from the construction surface, removing protruding parts, and filling cracks or dents with resin mortar; (S20) completely removing residues using shot blast or water jet to arrange the concrete construction surface; and (S30) vertically applying and penetrating 0.3 L/㎡ from the arranged concrete construction surface at a distance of 20 cm from the construction surface using a low-pressure (5 kg/cm2) sprayer.
